(With the occasional exception of yokels who post their links to dubious commercial websites. Speaking of "snake oil." But I try to stay on top of that.)<BR/><BR/>Scott... indeed you are right about electric cars just relocating the pollution-generating power source. And buyers - particularly environment-conscious buyers - should weigh that.<BR/><BR/>Stay tuned... more about "vehicle efficiency" soon to follow.Bikeboyhttps://www.blogger.com/profile/17379272663647894409noreply@blogger.comtag:blogger.com,1999:blog-198843833237575122.post-53378530429642642032008-07-31T14:00:00.000-06:002008-07-31T14:00:00.000-06:00I don't want to be a nay-sayer, but if there were ...I don't want to be a nay-sayer, but if there were simple solutions to these problems, these problems wouldn't <B>be</B> problems.<BR/><BR/>The math doesn't work on "electric" vehicles. Here in Idaho, about 87% of the electricity is generated by fish (hydro), but nationwide, about 70% is fossil-fuel based, meaning your "electric" car is still 70% hydrocarbon-powered. Electric cars may be zero emissions in themselves, but they still pollute at the power plant where their juice is generated.<BR/><BR/>Real-life electric power plants (fossil fuel, geothermal, and nuke are all about the same.) are about 30% efficient tops. Add to that transmission line losses, battery losses, and electric motor losses, plus the fact that you have to carry heavy batteries around, not to mention the increased energy to manufacture them, and electric cars aren't much, if at all, better than good old internal combustion engines running at 20% efficiency.<BR/><BR/>Oh, and if you placed a 100W solar panel on your roof and allowed it to charge a perfectly efficient battery for 8 hours, you'd generate enough electricity to run a 1 horsepower motor for about 1 hour.<BR/><BR/>Don't get me wrong. I love that people are thinking about energy and trying to find new ways to do things. I honestly believe that this is an opportunity for some budding young engineer to make a fortune thinking outside the box. Until then, remember that there are lots of snake oil salesmen out there.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-198843833237575122.post-44674706120680276182008-07-31T11:28:00.000-06:002008-07-31T11:28:00.000-06:00For something a little more practical and feasible...For something a little more practical and feasible than the Tesla, take a look at: http://afstrinity.com/ I have driven this one, and it is nice.

I recorded it last night and am planning to watch it soon.<BR/><BR/>With the program stating that cars are about 10% efficient I was wondering if any studies had been done regarding the efficiency of a bicycle. I did a quick search and found this <A HREF="http://www.sdearthtimes.com/et1199/et1199s13.html" REL="nofollow">link</A>.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-198843833237575122.post-48633307341917745912008-07-31T08:58:00.000-06:002008-07-31T08:58:00.000-06:00Pretty impressive figures about car and fuel consu...Pretty impressive figures about car and fuel consumption. Also very scary. <BR/><BR/>Battery technology is progressing but needs wider adoption by manufactures. Interestingly, Idaho has some of the largest and most pure Cobalt deposits.

(The Tesla uses Li-Ion batteries which are many times more powerful, power-to-weight, than lead acid batteries. But even they aren't comparable at this point to the power that can be stored in "hydrocarbon" form.) I guess that's why McCain is proposing a $250 million government prize. (Which IMO is ludicrous... the "prize" will be the billion$ raked in when the battery technology goes to market!
